To all whom t may concern.'

Be it ltnown that I, HARGUS G. SHELLY, a citizen of the United States, residing at Mulvane, in the county of Sumner and State 5 of Kansas, have .invented new and useful Improvement-s in .Boiler Cleaners, of which the following is a specification.

This invention relates to improvements in the boiler cleaner disclosed in Patent No.

l 794,015, dated July t, 1905, the same consisting of a chamber through which the boiler water circulates, and in which scale and other impurities are precipitated.

The invention has for its object to simplify the construction and to increase the efliciency of the device, and to this end it consists in a novel combination and arrangements of parts to be hereinafter described and claimed.

In order that the invention may be better understood, reference is had to the accompanying drawing, wherein- Figure 1 is an elevation of a boiler showing the connection of the device therewith; Fig. 2 is an enlarged central longitudinal section of the settling chamber, and Figs. 3 and 1lare cross-sections on the lines 3 3 and 4 4 of Fig. 2.

Referring specifically to the drawing 5 denotes the boiler to which the invention is applied, and as the structure of the boiler is immaterial to the invention, the same need not be described.

The sett-ling or precipitation chamber consists of a horizontally positioned cylindrical vessel 6 having one of its ends connected with the water space of the boiler by means of a pipe 7, and having at its other end a return connection 8 with said water space, said connection being a pipe which is connected to the top ofthe vessel. "Water from the boiler enters the vessel 6 through the inlet connection 7 and is allowed to flow back to the boiler through the connection 8. The

the boiler are made at such points that water is taken from the boiler just below the normal water line, and is returned at the lowest part of theV boiler, lso that there is a continuous circulation of the boiler water through the vessel 6. In the connection 8 is interposed a valve 9.

At that end of the vessel 6 to which the return pipe 8 is connected, is a depending sediment collecting branch or well 10 which is in open communication with the interior connections 7 and 8 with the water space of f of said vessel, so that the water circulating therethrough also lills the well. To the bottom of the well is connected a valved blowoiil pipe 11.

In the vessel 6 is located a series of vertical partitions 12 which are spaced from each other in the direction of the length of the vessel and rise from the bottom thereof but terminate short of the top. These partitions (itl are battle plates positioned vertically in the .i

pathv of the water flowing from the inlet to the outlet end of the vessel, and they serve to retard the ow ofwater through the vessel, and to catch and deflect downwardlythe particles of scale, dirt and other impurities present in the water, the same collecting behind the baille plates. The partitions 12 forming these battle plates have bottom openings 13 and smaller openings 1e above the same. The bottom openings 13 allow the dirt, etc. collecting behind the partitions to pass therethrough, and the dirt is gradually carried rearwardly to the well 10 and drops thereinto.

'In the well 10 are also mounted four vertically positioned baiiie plates 15 having perforations 16 and extending radially from the center, and from the top to the bottom of the well. These baille plates serve to prevent eddies in the well, which is desirable, as otherwise the mud and dirt in the well would be continuously kept stirred up and prevented from settling. The water in the well is in a quiescent state, and the mud and dirt are therefore permitted to settle to the bottom. It will also be noted that the well has a downward taper :so that its side wall is given a slant, which prevents mud and dirt well 10 and battle plates 12 and 15, can be a one-piece casting.

I claim:

1. A boiler cleaner comprising a horizontally disposed elongated vessel having an inlet connection at one end, the `other end of said vessel terminating in a dome shaped enlargement, said enlargement having an outlet connection, a depending sediment collecting well forming a continuation of said yessel' and said enlargement, said enlargement and. said Well having downwardly tapering Walls, a series of Vertical, radially disposed peifoiated baille plates in said Well and a series of vertical, transversely disposed baffle plates in said horizontally disposed vessel. l* Y 2. A boiler cleaner' comprising a horizontally disposed elongated `vessel having an inlet Connection at one end, the other end of saidyessel terminating in an enlargement having an outlet connection, a depending conical shaped sedi-ment collecting well foi'mng` a continuation ofsaidvessel and said enlargementy a series of' transverse perforated baffle plates in said Vessel, and a series of Vertical perforated 'baille platee extending fi'om the bottom of said Well to a.point. flush With the bottom Wall of said Vessel and from the side Walls of the Well to 20 a pointadj aeent thefeenter thereof.

In testimony whereof I affix my signature,
